A Framework for Providing User Level Quality of Service Guarantees in Multi-Class Rate Adaptive Systems

The problem of channel sharing by rate adaptive streams belonging to various classes is considered. Rate adaptation provides the opportunity for accepting more connections by adapting the bandwidth of connections that are already in the system. However, bandwidth adaptation must be employed in a careful manner in order to ensure that (a) bandwidth is allocated to various classes in a fair manner (system perspective) and (b) bandwidth adaptation does not affect adversely the perceived user quality of the connection (user quality). The system perspective aspect has been studied earlier. This paper focuses on the equally important user perspective. It is proposed to quantify user Quality of Service (QoS) through measures capturing short and long-term bandwidth fluctuations that can be implemented with the mechanisms of traffic regulators, widely used in networking for the purpose of controlling the traffic entering or exiting a network node. Furthermore, it is indicated how to integrate the user perspective metrics with the optimal algorithms for system performance metrics developed earlier by the authors. Simulation results illustrate the effectiveness of the proposed framework.

Mean waiting time evaluation of packet switches for centrally controlled PBX''s

The performance analysis of packet switched networks usually does not account for the loss of transmission bandwidth caused by the switch processing time. In wide area networks, where transmission channels are of the order of 64 kbps or less, this is a valid approach since switch processing time is negligible compared to average transmission times for packets. However, in Local Area Networks (LANs), the transmission channels are usually of the order of 1 mbps or greater and thus when evaluating the performance of a LAN that is based on a packet switch, it is necessary to consider the effect of the switch processing time which is now comparable to that of the average packet's transmission time. This paper investigates the effect of this processing time on network performance, and an exhaustive cyclic queueing algorithm to minimise this effect on overall network performance is discussed. An approximate analytical technique for evaluating the performance of such a LAN is derived. This technique makes it possible to do interactive calculations which can be used in the provisioning and configuring of such networks.     

丁腈橡胶在燃气介质中的老化性能测试研究

基于烘箱热空气老化试验方法,建立了一种能让试验样品处于流通气氛冲刷的闭合试验装置,对橡胶材料进行燃气环境中老化性能测试。选用丁腈橡胶为试样,测试其在不同温度、不同气氛下的老化性能,预测其使用时间。测试结果显示,采用空气气氛方法进行丁腈橡胶加速老化试验,预测的使用时间结果与实际使用时间的偏差在80%以上;燃气气氛冲刷环境下,丁腈橡胶在老化速率是热空气老化的2倍左右,且燃气气氛下的加速老化使用时间的预测结果与实际的偏差在±20%之内。
